DWC and NFT on the one pump

  1. Hi, I am thinking of doing DWC (sort of recycling) and NFT on the one pump, now I was thinking of splitting my pump (1000 gph) 2 ways and running one line to the gullies and another to my buckets. I am planning to pump water to the bottom of my buckets and at the top have a overflow that drains back into the reservoir, now my question is is it ok to use a pump like this, I mean will the pressure of the water in the buckets either damage my pump or restrict the inflow in some way? can water pumps be used like this? I hope this makes sense.
  2. You can do that, but if your pump is too strong, the overflow might not drain quick enough. I prefer to pump the water to the TOP of the buckets, and let it drain from the bottom of the buckets back to the reservoir. That way, the more FULL the buckets get, the more pressure is put on the drain line, and it drains faster as needed.
